THE WOODLANDS, Texas – Huntsman Corporation (NYSE: HUN) today announced that it has commissioned engineering design studies to increase its global capacity for the manufacture of methylene diphenyl diisocyanate (MDI) through investment at its Geismar, Louisiana site.

Commenting on the studies, Anthony P. Hankins, President of Huntsman Polyurethanes, said:“We are studying several options for expansion of the Geismar facility to ensure we can satisfy the strong demand in residential and commercial insulation and to maintain our position as the leading MDI supplier in the Americas region. With the benefits of US shale gas, the economics of investing in our US facilities has improved significantly.
